Composition for use in photoelectronic component packaging, packaging structure, and photoelectronic component

A composition for use in photoelectronic component encapsulated, comprising a photocurable monomer, a monofunctional or trifunctional silicon-containing monomer and an initiator, wherein the monofunctional silicon-containing monomer is as follows:

• wherein R1 is a substituted or unsubstituted C1 to C30 alkyl or alkoxy, or a substituted or unsubstituted C6 to C30 aryl;
• R2 is a single bond, a substituted or unsubstituted C1 to C20 alkylene, a substituted or unsubstituted C1 to C30 alkyleneoxy, a substituted or unsubstituted C6 to C30 arylene, or a substituted or unsubstituted C7 to C30 aryl alkylene;
• R3 is hydrogen, or a substituted or unsubstituted C1 to C30 alkyl;
• X1, X2, X3, and X4 are the same or different, and each independently selected from a substituted or unsubstituted C1 to C30 alkyl or alkoxy, or a substituted or unsubstituted C6 to C30 aryl;
• and n is an integer of 0~30, or the average is within 0~30;
• and
• the trifunctional silicon-containing monomer is as follows:
• wherein R1 is a substituted or unsubstituted C1 to C30 alkyl or alkoxy, or a substituted or unsubstituted C6 to C30 aryl;
• R2, R3 and R4 are a single bond, a substituted or unsubstituted C1 to C20 alkylene, a substituted or unsubstituted C1 to C30 alkyleneoxy, a substituted or unsubstituted C6 to C30 arylene, or a substituted or unsubstituted C7 to C30 aryl alkylene;
• R5, R6 and R7 are hydrogen, or a substituted or unsubstituted C1 to C30 alkyl;
• X1, X2, X3, X4, X5, and X6 are the same or different, and each independently selected from a substituted or unsubstituted C1 to C30 alkyl or alkoxy, or a substituted or unsubstituted C6 to C30 aryl;
• and n is an integer of 0~30, or the average is within 0~30, at least one of the silicon-containing monomer contains at least one C6 to C30 substituted or unsubstituted aryl bonded to a silicon atom.
