We successfully synthesized eight meso-aryl BODIPYs with 2,6-diethyl- or 1,2,6,7-tetraethyl substituents and characterized their photophysical properties. The steric hindrance resulting from the phenolic group in the meso-aryl moiety and the ethyl groups on the BODIPY core affected the synthesis of dipyrromethanes as an intermediate as well as the UV–Vis absorption and fluorescence emission of the
Provided is a compound represented by formula (1) or a pharmacologically acceptable salt thereof. (In the formula, A is C6-10 arylene, etc.; R1a, R1b and R1c each independently is a hydrogen atom, a halogen atom, a C1-4 alkyl group, a C1-4 alkoxy group, etc.; R2 is an optionally substituted C6-10 aryl group, an optionally substituted 5- to 12-membered monocyclic or polycyclic heteroaryl group, an optionally substituted C7-16 aralkyl group, etc.; m is 0, etc.; n is an integer of 0 to 2.)

A modular synthesis of polyfunctional dipyrrolemethanes is presented. Diverse side chains are introduced to 2-carboxypyrrole building blocks in two to four steps, resulting in a collection of substituted pyrroles that, when condensed in one step, give rise to diverse structural features.
