Boron chelate compounds, near-infrared light absorbing materials, thin films and organic electronics devices

摘要

PROBLEM TO BE SOLVED: To provide a compound, a photoelectric conversion element, an optical sensor, and an image pickup element having high thermal stability, easily usable workability, and having an absorption band in a near infrared light region. SOLUTION: A boron chelate compound of the formula (1) synthesized from an isoindole compound and a pyrrole compound as raw materials. (Z1 and Z2 are independently aromatic ring or heterocyclic divalent linking groups; R1 to R5 are independently H, aryl group, heterocyclic group, alkyl group, halogen; R6 is aryl group, heterocyclic group) [ Selection diagram] Fig. 2
