Delayed emission (DF) of fluorescence is generally observed either in solution or the crystalline state. In latter, well‐defined intermolecular interactions may play a significant role defining characteristics. Here, we present trialkoxy‐homotruxene that liquid at room temperature and compare its behavior with analog containing same π‐electron system. The DF due to triplet‐triplet annihilation (TTA) persists low temperatures (90 K). Accompanied by slightly shorter phosphorescence lifetimes,...
Compared to other photochromophores that show E-Z isomerisation, acylhydrazones are still relatively little explored in the field of liquid crystalline materials. To improve knowledge about this group and their viability as mesogenic core, herein a series 10 molecules were synthesised had thermal photoisomerisation properties investigated correlated structural changes. Mesomorphism was by POM, DSC, XRD SAXS techniques (using synchrotron radiation), while accompanied UV-Vis absorption...
O vírus COVID-19 se alastrou pelo mundo a partir do final de 2019 e é definido como uma síndrome respiratória aguda. Possui principal característica sua alta capacidade transmissão por ainda estar em curso, tão logo população apresentou suscetível infecção, o também demonstrou duas possibilidades ação, sendo elas forma branda que determinará magnitude dependerá sistema imunológico cada indivíduo. Por isso, série sintomas possíveis já foram diagnosticados profissionais da saúde cientistas,...
This research was carried out through the Center for Teaching, Research and Extension in Protection Disasters -CEPED Unioeste, focusing on importance of BR-277 which is largest highway state Paraná, being responsible tracing communication between East West part your daily flow several dangerous products (PP).The water collection points are located next to highway, potential areas risk, so that total supply some cities sometimes relies a single source, or spring.The study aimed connect dots...
