Abstract
A method of making a compound of Formula I′ comprises reacting a compound of the formula DLCHO, with a compound of the formula to produce the compound of Formula I′. Methods of using the compounds are also described, particularly as intermediates for the synthesis of porphyrin rods, which porphyrin rods are in turn useful for (among other things) the production of molecular memory devices.
Claims7
A method for the synthesis of a porphyrin rod, comprising the steps of:
- (a) providing a compound of the formula A′-L-B, wherein A is a 1,9-bis(thio)dipyrromethane, L is a linker group or covalent bond, and B is a dipyrromethane-1,9-dicarbinol;
- (b) providing a compound of the formula C-L-D;
- wherein C is a dipyrromethane, L is a linker group or covalent bond, and D is a 1,9-diacyldipyrromethane or surface attachment group;
- (c) condensing said compound of formula A′-L-B with said compound of formula C-L-D to produce an elongated compound of formula A-L-D, wherein A is a 1,9-bis(thio)dipyrrin, L is a linker group, and D said a 1,9-diacyldipyrromethane or surface attachment group, with said linker group comprising at least one porphyrinic macrocycle.
