Amino-substituted-1,1-dicyano-2,4-diaryl-1,3-butadiene chromophores: Synthesis and photophysical properties
نویسندگان
چکیده
A series of D-?-A chromophores based on allylidenemalononitrile electron-withdrawing group was designed. The influence the amino-electron-donating photophysical properties studied. These compounds, highly thermally stable, exhibit orange-red emission in solution and solid state. experimental results have been rationalized by theoretical DFT calculations. second order nonlinear optical were also studied using electric field induced harmonic generation (EFISH) method.

Rapid synthesis of 3-cyanopyridine-derived chromophores with two-dimensional tunability and solvatochromic photophysical properties.
Nicotinonitrile chromophores with two tunable functions, excellent photophysical properties and solvatochromic behaviour can be prepared quickly and efficiently by microwave-assisted tandem oxidation/Bohlmann-Rahtz heteroannulation followed by copper(I)-mediated N-arylation.
متن کاملPhotophysical properties of 5-substituted 2-thiopyrimidines.
The aim of the present work is to determine the influence of C5 substitution on the photophysical properties of 2-thiopyrimidines (2-TPyr). For this purpose, 2-thiouracil, 5-t-butyl-2-thiouracil and 2-thiothymine (TU, BTU and TT, respectively) have been selected as target thionucleobases for the experimental studies and, in parallel, for DFT theoretical calculations. The UV spectra displayed by...

متن کاملSynthesis and photophysical properties of meso-substituted bisporphyrins: comparative study of phosphorescence quenching for dioxygen sensing.
The 4,6-bis(10-mesityl-5,15-di-p-tolylporpyrinyl)dibenzothiophene (H4DPSN) free base was obtained in five steps from commercially available materials. The metalation of DPSN2- with zinc(II), copper(II), and palladium(II) led to three new homobimetallic systems, (Zn)2DPSN, (Cu)2DPSN, and (Pd)2DPSN, respectively. The cofacial structures of these molecules offer the possibility of having dioxygen ...
