Abstract: Use of an alpha -effective compound (I), and isoxazolidine compound (II), as an electron donor group in light-driven systems for charge separation, is claimed. Use of an alpha -effective compound of formula (X(R 1>)(R 3>)-Y 1>(R 2>)(R 4>)) (I), and isoxazolidine compound of formula (II), as an electron donor group in light-driven systems for charge separation, is claimed.

Full Definitions are given in the DEFINITIONS (Full Definitions) Field. Independent claims are included for: (1) a perylene bisimide-dyad compound of formula (III); (2) a perylene tetracarboxylic acid bisimide-nitrone compound of formula (IV); (3) the preparation of (III); and (4) the preparation of (IV), comprising reacting perylene bisimide-aldehyde with a hydroxylamine derivative. R1b-R11b : H, linear 1-37C-alkyl, in which 1-10 CH 2 units are optionally substituted by carbonyl, O, S, Se, Te, cis or trans-CH = CH-, and one CH unit is optionally substituted by N, acetylenic C?=C-groups, a divalent phenyl, divalent pyridine, divalent thiophene, divalent naphthalene (in which one or two CH group is optionally substituted by N) or a divalent anthracene (in which one or two CH group is optionally substituted by N), where 2-12 H atom of CH 2 is substituted by F, Cl, Br or I, CN or 2-18C-alkyl, in which 6 CH 2 unit is optionally substituted by carbonyl, S, O, Se, Te, cis or trans-CH=CH, in which one CH unit is optionally substituted by N, C?=C, a divalent phenyl, a divalent pyridine, a divalent thiophene, a divalent naphthalene, in which one or two CH group is optionally substituted by N, or a divalent anthracene, in which one or two CH group is optionally substituted by N, where 2-12 H atom of CH 2 group in the alkyl is optionally substituted by halo, CN, or 2-18C-alkyl, in which 6 CH 2 unit is optionally substituted by carbonyl, S, O, Se, Te, cis or trans-CH=CH, in which one CH unit is optionally substituted by N, -C?=C-, a divalent phenyl, divalent pyridine, a divalent thiophene, a divalent naphthalene, in which 1 or 2 CH group is optionally substituted by N, a divalent anthracene, in which one or two CH group is optionally substituted by N, F, Cl, Br, I or CN; and X 1> : 1-12 CH 2 units, which is optionally substituted by carbonyl, O, S, Se, Te, cis or trans-CH=CH-groups, in which one CH unit is optionally substituted by N, acetylenic C?=C-groups, a divalent phenyl, divalent pyridine, divalent thiophene, divalent naphthalene (in which one or two CH group is optionally substituted by N) or a divalent anthracene (in which one or two CH group is optionally substituted by N), where 2-12 H atom of CH 2 is substituted by F, Cl, Br or I, CN or 2-18C-alkyl, in which 6 CH 2 unit is optionally substituted by carbonyl, S, O, Se, Te, cis or trans-CH=CH, in which one CH unit is optionally substituted by N, C?=C, a divalent phenyl, a divalent pyridine, a divalent thiophene, a divalent naphthalene, in which one or two CH group is optionally substituted by N, or a divalent anthracene, in which one or two CH group is optionally substituted by N, where 2-12 H atom of CH 2 group in the alkyl is optionally substituted by halo, CN, or 2-18C-alkyl, in which 6 CH 2 unit is optionally substituted by carbonyl, S, O, Se, Te, cis or trans-CH=CH, in which one CH unit is optionally substituted by N, -C?=C-, a divalent phenyl, divalent pyridine, a divalent thiophene, a divalent naphthalene, in which 1 or 2 CH group is optionally substituted by N, or a divalent anthracene, in which one or two CH group is optionally substituted by N.
