A practical and convenient Co-catalyzed alkylation method for the facile introduction of various alkyl chains into organic electronically significant heteroaryl compounds, including thiophenes, furans, selenophenes, and pyrroles, is reported. Under well-optimized reaction conditions, a wide range of alkylated heteroaryl compounds have beeen efficiently prepared in moderate to good isolated yields.

A photoelectric conversion element has a structure where a hole transport layer, a photoelectric conversion layer, and an electron transport layer are held between a first electrode and a second electrode. The photoelectric conversion layer is a bulk heterojunction layer, and fullerene or a fullerene derivative is used as an n-type organic semiconductor. As a p-type organic semiconductor, a polymer represented by the following Expression is used. In the Expression, R
