“…6), including ACN, DMF, acetone, THF, chloroform, DOX, and EtOH. 3,4,34 It was found that DP 4 A 0 and DP 4 A 2 disperse liquid in DMF, DOX, chloroform, and THF and exhibited purple or yellow emission when excited with 365 nm UV light. 6,35,36 Thanks to the completely p-conjugated skeleton from the connection of the phenyl rings, DP 4 A 0 and DP 4 A 2 exhibited the strongest uorescence in THF (l ex ¼ 370 nm) and DOX (l ex ¼ 365 nm) suspensions, respectively.…”

“…7c, good linear S-V relationships were observed for DP 4 A 0 and DP 4 A 2 , and the K sv were up to 4 orders of magnitude greater than before the addition of o-NP, which indicated that DP 4 A 0 and DP 4 A 2 have high sensitivity to o-NP. 5,23,34,38,39 In addition, the LODs of DP 4 A 0 and DP 4 A 2 to o-NP are 5.73 Â 10 À9 and 7.36 Â 10 À9 mol L À1 , respectively, also indicating a high sensitivity to o-NP. 4-6 Fig.…”

“…34,[44][45][46][47] In order to assess the feasibility of PET from DP 4 A 2 and DP 4 A 2 to NACs, the lowest-unoccupied molecular orbital (LUMOs) energy levels and the highest occupied molecular orbital (HOMO) energy levels of DP 4 A 0 and DP 4 A 2 were calculated. 34 As shown in Fig. S8 and Table S2, † the LUMO levels of DP 4 A 0 and DP 4 A 2 are higher than that of the NACs, which allows for electron transfer from DP 4 A 0 and DP 4 A 2 to the NACs.…”

“…4 For example, the LUMO energy levels of PA and p-DNB are lower than that of DP 4 A 0 and DP 4 A 2 . 34,48 However, the LUMO levels are not the only factor affecting the PET process, it is also necessary to take into account the HOMO energy level of the NACs if it is lower than that of the CMPs. Hence, although the LUMO energies of DP 4 A 0 and DP 4 A 2 are lower than that of NB, DNT, p-NT, m-DNB, o-NP, and PhOH, a PET process can occur as well.…”

Nitrogen‐rich triazine‐based porous organic polyamines (POPa) synthesized via a one‐step polycondensation of melamine and 4,4′,4′′‐(1,3,5‐triazine‐2,4,6‐triyl)tribenzaldehyde is employed to synthesize Au and Pd nanoparticles well‐dispersed on POPa. The as‐prepared POPa‐supported Au NPs and Pd NPs (AuNPs@POPa, PdNPs@POPa) with a narrow size distribution show remarkable catalytic activity for the reduction of nitrobenzene compounds and organic dyes and the Suzuki–Miyaura coupling reaction, respectively. Benefitting from POPa the AuNPs@POPa and PdNPs@POPa catalysts can be readily recovered and reused almost without loss of activity. The nitrogen‐rich porous organic polyamines provide great opportunities to prepare functional metal nanocatalysts with potential in the heterogeneous catalysis field.

resulting in device efficiencies exceeding 18%. [11] Applications for π-conjugated polymers requiring high conductivity are also being widely explored, most notably using highly conductive poly(3,4-ethylenedioxythiophene) (PEDOT) in fields such as energy storage, tissue engineering, and textile-based electronics. [12][13][14][15][16] Applying π-conjugated polymers in electronics requires the complimentary development of favorable optoelectrical and mechanical properties. Molecular orbital alignments and polymer crystallization are of paramount importance. These interactions impact numerous properties, such as the polymer band energies, [17] charge-transfer processes, [18] redox potentials, [19] and photophysics. [20,21] Close chain-packing facilitates interpolymer charge transport, improving charge mobility in polymers as charges move by a hopping mechanism. [22] Additionally, the nanoscale morphology has a strong impact on the efficiency of photophysical processes, including exciton diffusion and dissociation, which are vital for OPVs and OPCs. [23] For wearable electronics flexibility and stretchability must also be considered. The brittle nature of crystalline materials produced from π-conjugated polymers is one of the major challenges that remains to be solved. The highly crystalline ordering caused by strong noncovalent interactions, chain interdigitation, or rigid polymer backbones leads to high tensile moduli and low stress loadings. [24] Many approaches have been explored to overcome this challenge including copolymerizing or blending conjugated polymers with elastomers and forming gels. [25][26][27][28][29] Programmed assembly (Figure 1) is an emerging bridge between our understanding of morphological ordering and functional materials. Programming order means to intentionally control ordering and morphology through inputs to achieve a desired functionality. It is a tool for rational material design, enabling structural complexity via a bottom-up approach to combine and enhance desirable material properties. This complexity results from orthogonal chemistries, which can be activated sequentially to build up structures in a stepwise manner. By this approach, each function would be met with its appropriate structure, as a morphology is selected to in order to achieve well-defined properties.Herein, we provide a review of innovative efforts being explored to program order in π-conjugated polymers from the π-Conjugated polymers have numerous applications due to their advantageous optoelectronic and mechanical properties. These properties depend intrinsically on polymer ordering, including crystallinity, orientation, morphology, domain size, and π-π interactions. Programming, or deliberately controlling the composition and ordering of π-conjugated polymers by well-defined inputs, is a key facet in the development of organic electronics. Here, π-conjugated programming is described at each stage of material development, stressing the links between each programming mode. Covalent programming is performed during p...
