AbstractBy 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, and10) were synthesized. The polymers were investigated by means
