Examples [of Substituent Group B] include alkyl groups (preferably with a carbon number of 1 to 30, more preferably with a carbon number of 1 to 20, and especially preferably with a carbon number of 1 to 10, such as a methyl, ethyl, isopropyl, tert-butyl, n-octyl, n-decyl, n-hexadecyl, cyclopropyl, cyclopentyl, and cyclohexyl); alkenyl groups (preferably with a carbon number of 2 to 30, more preferably with a carbon number of 2 to 20, and especially preferably with a carbon number of 2 to 10, such as a vinyl, allyl, 2-butenyl, and 3-pentenyl); alkynyl groups (preferably with a carbon number of 2 to 30, more preferably with a carbon number of 2 to 20, and especially preferably with a carbon number of 2 to 10, such as propargyl and 3-pentynyl); aryl groups (preferably with a carbon number of 6 to 30, more preferably with a carbon number of 6 to 20, and especially preferably with a carbon number of 6 to 12, such as phenyl, p-methylphenyl, naphthyl, and anthracenyl); a cyano group; heterocyclic groups (also including aromatic heterocyclic groups, preferably with a carbon number of 1 to 30 and more preferably with a carbon number of 1 to 12, with examples of the hetero atom including a nitrogen atom, an oxygen atom, a sulfur atom, a phosphorus atom, a silicon atom, a selenium atom, and a tellurium atom, and with concrete examples including pyridyl, pyrazinyl, pyrimidyl, pyridazinyl, pyrrolyl, pyrazolyl, triazolyl, imidazolyl, oxazolyl, thiazolyl, isoxazolyl, isothiazolyl, quinolyl, furyl, thienyl, selenophenyl, tellurophenyl, piperidyl, piperidino, morpholino, pyrrolidyl, pyrrolidino, benzoxazolyl, benzimidazolyl, benzothiazolyl, a carbazolyl group, azepinyl group, and silolyl group). These substituents may be further substituted, and examples of the further substituent include groups selected from the Substituent Group A2 described above. 2 Translator's note: “Substituent Group B” is probably intended in the original rather than “Substituent Group A.”
