A method for producing a dendrimer having a structural repeating unit which is represented by formula (1) and which contains a linear portion including a thienylene moiety and a branch portion Y formed of an optionally substituted trivalent organic group. The method is based on the convergent method and includes reaction step 1 of converting α-position hydrogen of the thiophene ring of a thienylene-moiety-containing compound (a) for forming end moieties to an active group V1 which undergoes Suzuki cross-coupling reaction, to thereby form compound (b); reaction step 2 of subjecting a compound (c) to Suzuki cross-coupling reaction with the compound (b), to thereby yield compound (d), the compound (c) having a linear portion and a branch portion Y and having, at the branch portion Y, two active groups V2 which undergo Suzuki cross-coupling reaction with the active group V1; reaction step 3 of converting α-position hydrogen of the thiophene ring of the thus-formed compound to an active group V1 which undergoes Suzuki cross-coupling reaction, and reacting the compound (c) with the active group V1, to thereby form a dendron of a subsequent generation; and a step of repeating the reaction step 3 in accordance with needs, to thereby form a dendrimer.

The visible light mediated metal-free approach has been developed for C–H arylation and borylation employing anilines as starting material. A series of -aryl corroles (A and AB type) were synthesized and their catalytic potential was tested in blue light and sunlight. The method includes substituted anilines as source of expensive aryl diazonium salts and utilizes only 0.5 to 1 mol% of corrole catalyst
