    摘要： Gelators gel a variety of nonpolar and polar liquids. Moreover, gelation of various monomers with subsequent polymerization of the gelled monomers forms organic zeolites and membrane materials. An ionic gelator includes salts of compounds of the formula (I):�R.sup.1 R.sup.2 R.sup.3 X-R.sup.4 !.+-.Y.-+. (I)where R.sup.1, R.sup.2 and R.sup.3 are the same or different hydrogen or organic groups including alkyl groups, alkenyl groups, alkynyl groups, aryl groups, arylalkyl groups, alkoxy groups, aryloxy groups; X is a Group IIIA or Group VA element; R.sup.4 is a steroidal group, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an arylalkyl group, an alkoxy group or an aryloxy group; and Y is a Group IA or Group VIIA element or one-half of a Group IIA or VIA element, that is, a divalent counterion. The gelling agent composition may include a single isomer or mixtures of isomers of the formula (I). A non-ionic gelator also includes compounds of the formula:R.sup.1 R.sup.2 R.sup.3 X (II)where R.sup.1, R.sup.2, R.sup.3 and X are defined as above.

    摘要： Compositions including biocidal reagents and articles treated or coated therewith are described. The compositions can be used to make passive biocidal surfaces. Exemplary biocidal reagents include visible light-absorbing polyelectrolytes which act as passive biocides upon exposure to radiation, including relatively weak “background” radiation such as natural light sources (e.g., indirect sunlight) and artificial light sources. Methods of treating or coating surfaces with the compositions are also described.
