.pi.-Conjugated systems with unique electronic structure: a case of planarized 1,3-connected polyarylmethyl carbodianion and stable triplet hydrocarbon diradical
摘要:
The effect of ''planarization'' on pi-conjugated 1,3-connected polyarylmethyls in connection with the electronic structure and magnetic properties is examined. The synthesis, ESR and UV-vis spectroscopy, voltammetry, and magnetic studies of triplet diradical 6(2.) are reported. The corresponding dianion 6(2-), 2M+ (M = Li, K) is studied using NMR and UV-vis spectroscopy.

A pattern forming method includes forming a film using an actinic ray-sensitive or radiation-sensitive resin composition, exposing the film with active light or radiation, and developing the exposed film using a developer including an organic solvent, in which the actinic ray-sensitive or radiation-sensitive resin composition contains a compound having a partial structure represented by General Formula (I).

We describe the synthesis and electronic properties of ladder oligomers of poly(m-aniline) that may be considered as derivatives of azaacenes with cross-conjugated π-systems. Syntheses of ladder oligo(m-aniline)s with 9 and 13 collinearly fused six-membered rings employed Pd-catalyzedaminations and Friedel–Crafts-based ring closures. Structures were confirmed by either X-ray crystallography or correlations
