摘要	NEW MATERIAL: A compound of the formula [R 1 , R 4 -R 5 , and R 8 are each H, a 1-12C (hetero)aryl, or an alkyl; R 2 -R 3 and R 6 -R 7 are each a 1-12C alkyl(thio), an aryl(thio), an alkylseleno, an arylseleno, an alkyltelluro, an aryltelluro, H, a halogen, hydroxyl, an alkoxy, or amino; R 9 -R 12 are each a 1-12C alkyl, an alkoxy, H, a halogen, or cyano; (n) is 0-2; as for X 1 and X 2 , one is either Se or Te but they consist of mutually different chalcogenides; Z - is a Lewis base)]. EXAMPLE: 2,6-di-t-Butyl-4-[3-(2,6-di-t-butyl-4H-telluropyran-4-ylidene)-1-propen-1-yl] selenopyrylium chloride. USE: A photomechanical treatment for cancer cells. PROCESS: The compound is produced by mixing a compound of the formula of which Z - is an anion other than a Lewis base with an ion exchange resin containing Lewis bases, and exchanging non-Lewis base anions with Lewis bases.
