NEW MATERIAL:4,4'-Bis(hydroxymethyl)-2,2'-bipyridine shown by formula I. USE:A photosensitizer using solar energy. PREPARATION:4,4'-Dimethyl-2,2'-bipyridine shown by formula II is oxidized with KMnO4 in water to give a 4,4'-dicarboxy derivative, which is chlorinated with SOCl2 under reflux for 3-4hr, successively esterified with CH3OH under reflux for 2-4hr to give a 4,4'-bis(methoxycarbonyl) derivative, which is reduced with NaBH4, etc., to give a compound shown by formula I.
