Polymere charge‐transfer‐komplexe auf der basis von polyvinylalkoholacetalen, 5

By reaction of poly[2‐(1‐naphthyl)‐1,3‐dioxan‐4,6‐diylmethylene] (3), poly[2‐(2‐naphthyl)‐1,3‐dioxan‐4,6‐diylmethylene] (5), poly[2‐(9‐isobutyl‐3‐carbazolyl)‐1,3‐dioxan‐4,6‐diylmethylene] (7) and poly[2‐((S)‐9‐(2‐methylbutyl)‐3‐carbazolyl)‐1,3‐dioxan‐4,6‐diylmethylene] (9) with 3,5‐dinitrobenzoylchloride (12) or 4,5,7‐trinitro‐9‐fluorenone‐2‐carboxylic acid chloride (2) polymeric intramolecular charge‐transfer‐complexes (4a, 4b, 6, 8a, 8b, and 10) were synthesized. The polymers were investigated by means of UV or remission spectroscopy as well as by differential thermal analysis.
