Abstract

From 2,3,5,6‐tetramethylthiazolo[4,5‐f]benzothiazoldiium diperchlorate (9) and the ortho esters 2ad or 1,1,3,3‐tetramethoxypropane (4) polymeric cyanines with trimethine (10a), substituted trimethine (10bd), respectively pentamethine units (11) were synthesized. Model compounds (3ae, 5, 7ad, 8) were prepared from 1a, 1b and 6, analogously. The structures were confirmed by elemental analyses, IR, and electronic spectra. In addition, the model compounds were characterized by their ^1^H NMR and mass spectra.

## Abstract An equipment for measuring the photoconduction of polymeric material is described comprehensively. The electrical dark conductivities (σ ≤ 2,5 · 10^−9^ Ω^−1^ · cm^−1^) and the photoconduction (__I__~phot~ ≤ 2,0 · 10^−10^ A) were studied for polymeric cyanines and corresponding model com
