Abstract:
1. Compounds of the formulae wherein R 1 , R 2 , R 3 , and R 4 each, independently of the others, is (i) a hydrogen atom, (ii) an alkyl group, (iii) an aryl group, (iv) an arylalkyl group, or (v) an alkylaryl group, wherein R 1 and R 2 can be joined together to form a ring, wherein R 3 and R 4 can be joined together to form a ring, and wherein R 1 , R 2 , R 3 , and R 4 can each be joined to a phenyl ring in the central structure, a and b each, independently of the others, is an integer which is 0, 1, 2, or 3, c is an integer which is 0, 1, 2, 3, or 4, each R 5 , R 6 , and R 7 , independently of the others, is (i) an alkyl group, (ii) an aryl group, (iii) an arylalkyl group, (iv) an alkylaryl group, (v) a halogen atom, (vi) an ester group, (vii) an amide group, (viii) a sulfone group, (ix) an amine group or ammonium group, (x) a nitrile group, (xi) a nitro group, (xii) a hydroxy group, (xiii) a cyano group, (xiv) a pyridine or pyridinium group, (xv) an ether group, (xvi) an aldehyde group, (xvii) a ketone group, (xviii) a carbonyl group, (xix) a thiocarbonyl group, (xx) a sulfate group, (xxi) a sulfide group, (xxii) a sulfoxide group, (xxiii) a phosphine or phosphonium group, (xxiv) a phosphate group, (xxv) a mercapto group, (xxvi) a nitroso group, (xxvii) an acyl group, (xxviii) an acid anhydride group, (xxix) an azide group, (xxx) an azo group, (xxxi) a cyanato group, (xxxii) an isocyanato group, (xxxiii) a thiocyanato group, (xxxiv) an isothiocyanato group, (xxxv) a urethane group, or (xxxvi) a urea group, wherein R 5 , R 6 , and R 7 can each be joined to a phenyl ring in the central structure, R 8 , R 9 , and R 10 each, independently of the others, is (i) a hydrogen atom, (ii) an alkyl group, (iii) an aryl group, (iv) an arylalkyl group, or (v) an alkylaryl group, provided that the number of carbon atoms in R 1 +R 2 +R 3 +R 4 +R 5 +R 6 +R 7 +R 8 +R 9 +R 10 is at least about 16, provided that when at least one of the following of (a), (b), and (c) is true: (a) the number of carbon atoms in R 1 +R 2 +R 3 +R 4 is at least about 42, (b) at least one of R 1 , R 2 , R 3 , and R 4 is a group of the formula wherein R 41 and R 42 each, independently of the other, is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group, or (c) at least one of R 1 , R 2 , R 3 , and R 4 is a branched alkyl group having at least about 19 carbon atoms.
