Proiectul isi propune continuarea unor cercetari in domeniul fotopolimerilor, preponderent abordati de catre o parte din membrii echipei, pentru a valorifica experienta dobandita in sinteza monomerilor cu structuri complexe capabile de a forma arhitecturi polimere si materiale compozite cu proprietati controlabile destinate unor aplicatii de varf (optica, fotonica, microlitografie, biologie, medicina).
Obiectivele proiectului:
Obiectivul general:
Cresterea vizibilitatii internationale a grupului prin marirea numarului de publicatii in reviste cu indice de impact ridicat si formarea de tineri specialisti in domeniul sintezei organice cu aplicatii in chimia polimerilor si a compozitelor hibride
Obiective stiintifice:
• proiectarea si sinteza de noi fotopolimeri si compozite hibride cu grupari fotoactive (izomerizabile, clivabile, luminescente) si/sau mezogene
• investigarea unor polimeri cu top ografie si masa moleculara controlabila, continut de grupari cromofore prestabilit in interactie cu radiatia UV/laser
• stabilirea de corelatii structura-proprietati fizico-chimice, comportare foto(chimica)fizica, mecanisme de reactie, parametri de ablatie
• perspective de aplicare in domenii de varf (materiale fotocrome/fotoluminescente, elemente microoptice, chemosenzori, etc)
