A covalent triazine-based framework from tetraphenylthiophene and 2,4,6-trichloro-1,3,5-triazine motifs for sensing o-nitrophenol and effective I₂ uptake

Abstract

A covalent triazine-based framework with a tetraphenylthiophene (TTPT) backbone was prepared by the AlCl3 catalyzed Friedel–Crafts reaction of commercially available material 2,4,6-trichloro-1,3,5-triazine with tetraphenylthiophene in dichloromethane.

Meso/Microporous Carbons from Conjugated Hyper-Crosslinked Polymers Based on Tetraphenylethene for High-Performance CO2 Capture and Supercapacitor

“…In addition, the N 2 adsorption isotherms of TPE-CPOP1 and TPE-CPOP2 at high-pressure values possesses a hysteresis loop, which indicates that the obtained polymer framework contains a mesoporous and microporous structure. Furthermore, the hysteresis loop for both materials does not close, which could be attributed to the flexibility network structure and the swelling of the frameworks during gas adsoprtion by elastic deformations [ 52 ]. The BET surface areas of TPE-CPOP1 and TPE-CPOP2 were found to be 489 and 146 m 2 g −1 , respectively, and their pore volumes were found to be 0.269 and 0.1 cm 3 g −1 at P/P 0 = 0.996, respectively.…”

“…Hyper-crosslinked polymers (HCPs) [ 28 , 29 , 30 , 31 , 32 , 33 ], covalent organic frameworks (COF) [ 34 , 35 , 36 , 37 , 38 , 39 , 40 ], conjugated microporous polymers (CMPs) [ 41 , 42 , 43 , 44 , 45 ], and polymers of intrinsic microporosity (PIMs) are considered as types of microporous organic polymers (MOPs) [ 46 , 47 , 48 , 49 ]. As mentioned above, HCPs are considered as a kind of porous material that can be easily synthesized through the Friedel–Crafts alkylation reaction of rigid aromatic monomers with an external crosslinker such as formaldehyde dimethyl acetal, 1,3,5-trichlorotriazine, and 1,4-bis(chloromethyl)benzene [ 50 , 51 , 52 ]. Compared with other microporous material such as activated carbon, HCPs can be synthesized by low-cost monomers, catalysts, and suitable reaction conditions [ 53 , 54 ].…”

“…Compared with other microporous material such as activated carbon, HCPs can be synthesized by low-cost monomers, catalysts, and suitable reaction conditions [ 53 , 54 ]. In addition, HCPs materials feature easy functionalization, good chemical and thermal properties, microporous nature, and large surface areas [ 50 , 51 , 52 , 53 , 54 ]. Nowadays, the preparation of porous carbon materials has attracted much attention due to their interesting properties such as excellent electrical conductivity, high surface areas and high pore volumes, and good chemical, thermal, and mechanical stabilities [ 55 , 56 , 57 , 58 , 59 ].…”

Synthesis of conjugated polymers via cyclopentannulation reaction: promising materials for iodine adsorption

“…The 200 wt% iodine uptake value of CPP2 is superior to those of polymers reported in the literature, and notable among these are nitrogen-rich triptycene-based materials (NTP, 180 wt%), 59 calix [4]arene-based 2D macromolecules (CX4-NS, 114 wt%), 60 porphyrin and pyrene-based conjugated microporous polymers (Por-Py-CMP, 130 wt%), 61 nitrogen-containing materials (NRPPs, 192 wt%), 57 JLUE covalent organic polymer (JLUE-COP-3, up to 90.29%), 62 conjugated microporous polymers with thiophene units (SCMPs, 222 wt%), 34 hierarchically porous adamantane-based macromolecules (202 wt%), 63 triazine-based covalent frameworks (TTPT, 177wt%), 64 fluorine-enriched polymers (FCMP-600@1-4, up to 141 wt%) 65 and many others. 66,67 The iodine adsorbed by CPP1-3 could be released by simple heating of these latter polymers in air at 125°C.…”

Fluorinated Iron(ii) clathrochelate units in metalorganic based copolymers: improved porosity, iodine uptake, and dye adsorption properties

“…The 200 wt% uptake for CCP2 and CCP5 to iodine is promising because of the several advantages these copolymers present, namely, their versatile synthesis from commercially available synthons and the ease of their isolation, especially when compared to the polymer networks reported in the literature which require intricate synthetic and/or purication steps and whose iodine adsorption values are either lower or approximately equal to the ones presented herein. [53][54][55][56][57][58][59][60][61][62][63][64][65] Iodine-containing copolymers CCP1-5 (I 2 @CCP1-5) underwent desorption by simple heating in air at 120 C. The complete wt% of iodine released from I 2 @CCP1-5 samples was recorded at different time intervals (Fig. 7 and Table 2).…”
