“…According to previous research, pyrenyl chalcone derivative shows a good property as the electron donating group (EDG) attributes to the high energy π-π * transitions at the range of 320-400 nm [13]. Pyrenyl chalcones substituted with suitable combination of electron donor (-Me, -OMe, -OH, -NH 2 and -S) and acceptor (-F, -Cl, -Br, -CN and -NO 2 ) on another side of phenyl rings form the structure of D-π-A and D-π-D architecture, respectively [14][15][16]. According to the previous study, the conjugation of acceptor moiety in pyrenyl chalcone has improved the electron delocalization compared to the attachment of electron donor group to the structure of pyrenyl chalcone [17].…”

Photovoltaic studies in DSSC have continued to be fascinated by chalcone derivatives because of their straightforward synthesis, green synthetic process and low toxicity properties using Claisen-Schmidt condensation method. In this report, the implementation of the newly synthesized pyrenyl chalcone derivatives, Py1 and Py2 as dye-sensitizers and the characterization studies are further discussed. The grown crystals are characterized via several spectroscopic analyses such as ATR, 1H and 13C NMR and UV–vis analyses. The UV–vis analysis shows a lower energy gap in Py1 (2.79 eV) in comparison to Py2 (2.90 eV) which further indicates better flow of charge transfer. The analysis of crystal packing reveals the arrangement of head-to-head by intermolecular π—π contacts and head-to-tail via intermolecular C–H···O interactions in Py1 and Py2, respectively. The intermolecular interactions act to stabilize the crystal structure and further improve the charge transfer within the dyes and enhancement of DSSC efficiency. In electrochemical analysis using cyclic voltammetry (CV), Py1 and Py2 are found in the suitable HOMO and LUMO energy levels which confirms their applicability as photosensitizer materials. After the fabrication process, DSSC layers are continued for FESEM and EDX analyses before proceeding for the performance study. The Py1 with D-π-A architecture has significantly revealed a higher efficiency than D-π-D structure of Py2.

“…Organo-crystals are specified by its magnificent nonlinear/linear responses that made them a potential nominee for optoelectronic devices like optocommunicator, optoswitchers and memory processors (Davanagere et al 2019;Karnan et al 2019;Amutha et al 2017a, b). Most of noncentro/symmetric crystals have a high 2nd harmonic generation (SHG) efficiency surpass centrosymmetric ones.…”

Both theoretical and experimental studies are briefly discussed to shed lights on crystal shape, FT-IR, electronic, and non-linear opto-response (NLO) characteristics of ethyl4-(3,4-dimethoxyphenyl)-6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate (MTTHPC). Theoretical FT_IR results are in a proper concord with recorded measurements. MTTHPC has TDM (4.78 Debye) and a doublet spins that splits original FMOs into alpha(↑, 2.44 eV) and beta(↓, 1.28 eV) offsets, respectively. MTTHPC is a potential competitor for finest perovskite solar cells (MAPbI 3 /Au-nanospheres) that possess a band offset ( 3.1 eV ) with conversion-efficiency 24.84%. MTTHPC may be the next chapter for unique avalanche photodetectors (APD). MTTHPC 1st order hyperpolarizability is 14.15 * 10 −30 esu , surpass reference urea (≈ 40 urea , urea = 0.3728 * 10 −30 esu ). Briefly, MTTHPC may be admitted as the next stage in forthcoming NLO technology.
