Ester compound and preparation method therefor and uses thereof

An ester compound of formula (I):

• wherein,
• the plural L′ groups, identical to or different from each other, are each independently selected from C1-16 linear or branched alkylene;
• the plural R groups, identical to or different from each other, are each independently selected from a single bond, a C1-20 linear or branched alkylene;
• p is 1, 2, or 3;
• the plural L groups, identical to or different from each other, are each independently selected from a hydrogen atom, an optionally substituted C1-10 linear or branched alkyl, a group of formula (II), a group of formula (III), with the proviso that at least two L groups are selected from a group of formula (III),
• wherein,
• the R′ group is selected from a single bond, a C1-10 linear or branched alkylene, and the carbon atoms bonded to L are at most directly bonded to one oxygen atom,
• the plural R″ groups, identical to or different from each other, are each independently selected from a single bond and a C1-10 linear or branched alkylene;
• the R0 group is selected from H, an optionally substituted C1-10 linear or branched alkyl;
• m is 1;
• the plural A groups, identical to or different from each other, are each independently selected from a group of formula (III-A), methylene and ethylene, with the proviso that at least one A group is selected from a group of formula (III-A);
• and
• wherein the plural R0′ groups are each independently an optionally substituted C1-15 linear or branched alkyl, said substituents are selected from halogen atoms, hydroxy, amino, C1-6 linear or branched alkyl, C6-10 aryl, and C3-10 cycloalkyl.
