TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Material: The base material is glass.    TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Method: The light harvesting method may comprises applying one or more components from the cross-linked pair or quartet of polymerizable monomer units, respectively, to a surface; polymerizing the units in situ, optionally in the presence of another monomer, polymer or copolymer; applying light to the resultant surface, or exposing the surface to light; and capturing the resultant current.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Material: The base material is metal.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The other monomer unit is a substituted aromatic or hetero aromatic ring. It is preferably aromatic (preferably benzene), substituted aromatic (preferably substituted benzene), aniline, substituted aniline, thiophene, substituted thiophene, oligothiophene, furan, substituted furan, pyrrole or substituted pyrrole, preferably terthiophene.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The polymer is a copolymer of the monomer units and at least one other monomer unit. It has been prepared by electro-polymerization. The electrofunctional unit is coordinated with metal, preferably zinc. The ratio of P to other monomer unit is 1:2. The cross-linked pair of monomer units, cross-linked quartet of monomer units, polymer, or copolymer further includes a solubilizing group and SO3- moiety.Preferred Method: The preparation method further comprises adding at least one other monomer unit prior to polymerization. The polymerization is by chemical or electrochemical oxidation.    TECHNOLOGY FOCUS - TEXTILES AND PAPER - Preferred Material: The base material is textile. Preferred Definition:    Q, Q'=substituted aromatic rings or hetero aromatic rings from substituted aromatic, aniline, substituted aniline, thiophene, substituted thiophene, oligothiophene, furan, substituted furan, pyrrole or substituted pyrrole;    L, L'=a group of formula (a) or (b);    n, m=0-3;    Ar=phenylene, naphthylene, polyarylene, heteroarylene or ferrocenyl or similar metal sandwich complex; and    P=optionally substituted porphyrin, optionally substituted phthalocyanine or tetranitrogen-containing macrocycle.    The Q and Q' are of molecular dimensions adequate to permit polymerization of the monomer units of the cross-linked pair of polymerizable monomer units as a homopolymer.    EXAMPLE - A solution of Zn(OAc)2asterisk2H2O (42.9 mg) in methyl hydroxide (MeOH, 1 ml) was added to a solution of bisterthienylporphyrin (II) (177 mg) in trimethyl chloride (CHCl3, 18 ml) with stirring at RT. The reaction was deemed complete by TLC (Rf= 0.25, silica, dimethyl chloride (CH2Cl2): hexane (1:2)) after 30 minutes. The crude product was precipitated with MeOH and the resulting solid recrystallized from CH2Cl2/MeOH giving 5,15-bis((2',2:5,2-terthiophen)-3-yl)-2,8,12,18-tetra-(n-butyl)-3,7,13,17-tetramethylporphyrinato zinc(II) (189 mg, 100%).
