Disclosed is a composition comprising an organogel which comprises: (a) an alkylated aromatic acid compound of the formula;
or mixtures thereof, wherein R1, R2, R3, R4, and R5 each, independently of the other, are hydrogen, alkyl, aryl, arylalkyl, or alkyl, provided that at least one of R1, R2, R3, R4, and R5 is —X—Rc, wherein —X— is a linking group between Rc and the aromatic group and Rc is alkyl; and (b) an organic liquid. |

1. A composition comprising an organogel consisting of a) an alkylated aromatic acid and b) an organic liquid solvent entrapped within the organogel wherein the liquid is rigidified:
wherein the alkylated aromatic acid compound is of the formula or mixtures thereof, wherein R1, R2, R3, R4, and R5 each, independently of the other, is: (A) hydrogen atoms; —COOH; (B) alkyl groups, including substituted and unsubstituted alkyl groups, wherein hetero atoms either may or may not be present in the alkyl group; (C) aryl groups, including substituted and unsubstituted aryl groups, wherein hetero atoms either may or may not be present in the aryl group; (D) arylalkyl groups, including substituted and unsubstituted arylalkyl groups, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of the arylalkyl group; or (E) alkylaryl groups, including substituted and unsubstituted alkylaryl groups, wherein hetero atoms either may or may not be present in either or both of the alkyl portion and the aryl portion of the alkylaryl group; provided that at least one of R1, R2, R3, R4, and R5 is —X—Rc, wherein: (F) —X— is a linking group between Rc and the aromatic group, wherein —X— is selected from the group consisting of (i) —O—; (ii) —S—; (iii) —SO—; (iv) —SO2—; (v) —NH—(C═O)—; (vi) —(C═O)—NH—; (vii) —NH—(C═S)—; (viii) —(C═S)—NH—; (ix) —NH—; (x) —NH—(C═O)—NH—; (xi) —NH—(C═S)—NH—; (xii) —NH—(C═O)—O—; (xiii) —O—(C═O)—NH—; (xiv) —NH—(C═S)—O—; (xv) —S—(C═O)—NH—; (xvi) —NH—(C═S)—O—; (xvii) —NH—(C═S)—S—; (xviii) —O—(C═S)—NH—; (xix) —S—(C═S)—NH—; (xxi) —(C═O)—S—; (xxii) —O—(C═O)—; (xxiii) —S—(C═O)—; (xxiv) —(C═S)—O—; (xxv) —(C═S)—S—; (xxvi) —O—(C═S)—; (xxvii) —S—(C═S)—; (xxviii) —O—(C═O)—O—; (xxix) —O—(C═S)—O—; and (G) Rc is an alkyl group, including substituted and unsubstituted alkyl groups, wherein hetero atoms either may or may not be present in the alkyl group; with the provisos that: (1) when the compound is of the formula either R1 is not or n is not 9, 10, or 11; (2) when the compound is of the formula n is not 9, 10, or 11; (3) when the compound is of the formula either R1 is not —COOH or Rc is not wherein n is 8 to 10; and (4) when the compound is of the formula either R1 is not —COOH or Rc is not wherein n is from 8 to 10; and wherein alkylated aromatic acid compounds self-assemble in the presence of the organic solvent to form the organogel, wherein the organogel exhibits a gel-to-sol transition temperature of from about 65° C. to about 110° C. |
