Hromofori un luminofori uz β,β’-triketonu un β-diketonu bāzes

Abstract

Promocijas darbā iegūti jauni Eu3+ organiskie tris, Lūisa bāzes un tetrakis kompleksi ar dažādiem β,β’-triketonātiem un β-diketonātiem (2-acildimedona, 2-acil-1,3-indandiona un dibenzoilmetāna atvasinājumiem), kuriem noteiktas un salīdzinātas emisijas īpašības šķīdumos, pulverveidā un polimērplēvītēs. Izpētītas kompleksa struktūras un tetrakis kompleksa katjona izmēra ietekme uz emisijas īpašībām. Izgatavoti divi OLED ar Eu3+ kompleksiem ar dibenzoilmetāna atvasinājumu ligandiem. Pirmo reizi novērota agregācijas pastiprinātā emisija Eu3+ kompleksiem ar dibenzoilmetāna atvasinājumu ligandiem. Promocijas darbā arī iegūta virkne 2-cinnamoildimedona un 2-cinnamoil-1,3-indandiona atvasinājumu, izpētītas un salīdzinātas to optiskās, elektroķīmiskās, termiskās īpašības. Izmantojot kvantu ķīmijas aprēķinu programmu “ORCA”, aprēķināta savienojumu pamatstāvokļa ģeometrija un HOMO/LUMO orbitāles. Sistemātiski izpētīts dažādu amino-donoro grupu un akceptoro grupu ietekme uz savienojumu īpašībām.
