Various uses an include uses in gels, inks, and membranes.
Claims15
A trianglamine based compound of formula I:
- wherein,
- each A independently represents a substituted or unsubstituted 4 to 18-membered aryl or heteroaryl linker,
- each Y1 independently represents a bond or forms, together with the nitrogen of the trianglamine, a functional group chosen from urea (—N—C(O)—NH—), carbamate (—N—C(O)—O—) and amide (—N—C(O)—),
- each R1 independently represents a mono or bifunctional radical chosen from H, a linear or cyclic, optionally branched, saturated or unsaturated, optionally substituted C1 to C30 hydrocarbon chain optionally comprising a heteroatom such as O or N, an optionally substituted C1 to C20 alkylaryl, an optionally substituted C1 to C20 alkylheteroaryl group, a substituted or unsubstituted C4 to C6-membered aryl or heteroaryl group or a polyether comprising from 2 to 100 monomers,
- at least one —Y1—(R1)a—(Y2)b—(R2)c radical is different from H,
- each a=0 or 1,
- each b=0 or 1,
- each c=0 or 1,
- in a substituent —Y1—(R1)a—(Y2)b—(R2)c at least one from a, b and c is different from 0,
- each Y2 independently represents a functional group chosen from hydroxyl (—OH), ester (—C(O)O— or —O—C(O)—), diester (—O—C(O)—R5—C(O)—O—, in which R5 is a C1 to C8 alkyl chain), carbamate (—NH—C(O)—O— or —O—C(O)—NH—), ether (—O—), amine (—NH— or —NR— in which R is a protecting group such as Boc), acrylate (CH2=CHC(O)O—), methacrylate (CH2=C(CH3)C(O)O—), —SiOR43 in which R4 is a C1 to C4 alkyl chain, halo group, a maleinimido group, a silicagel and a resin,
- each R2 independently represents a linker of formula II:
- wherein,
- R3 represents a mono-, bi-, tri- or tetrafuntional radical comprising from 1 to 500 carbon atoms, optionally comprising hetero atoms such as O, N, Si or halo,
- the represents the point of attachment to Y2 and
- represents the point of attachment to another trianglamine based compound of formula I,
- Y′2 is defined as Y2, R′1 is defined as R1, Y′1 is defined as Y′, a′=0 or 1, b′=0 or 1 and d is an integer from 0 to 3.
A process of synthesis of a trianglamine of formula III comprising the steps of:
- a) reacting 1,2-di aminocyclohexane with a compound of formula V:
- wherein, A is defined as above,
- b) reacting the compound obtained in step a) with NaBH4,
- and obtaining the compound of formula III.
