The 19th International Electronic Conference on Synthetic Organic Chemistry, doi: 10.3390/ecsoc-19-a037
The photochemistry of the vinyl substituted (E)-3-(anthran-9-yl)propenoates and (E)-9-(aroylethenyl)anthracenes as well of their reduced derivatives has been studied at lambda = 254 nm and at lambda= 352 nm. At lambda = 254 nm and lambda= 352 nm, the 9-vinyl substituted anthracenes undergo E/Z-isomerization, while their reduced derivatives undergo [4+4]-dimerisation reactions at lamda = 352 nm. An X-ray crystal structure shows the [4+4]-photoadducts to be head-to-tail. The photochemistry of cycloadducts of (E)-3-(anthran-9-yl)propenoates and (E)-9-(aroylethenyl)anthracenes with maleimides and other activated dienophiles show a number of reactions, among them retro-cleavage of the cycloadducts to the respective anthracenes.
CONFERENCE-ARTICLE 2 Reads 0 Citations New Heat Transfer Fluids (HTFs) for Solar Thermal Applications Published: 31 October 2013
The 3rd World Sustainability Forum, doi: 10.3390/wsf3-d002
Heat transfer fluids (HTFs) are used widely in many industrial processes. They collect and transport thermal energy in process heating, metal working, machine cooling with applications in the aerospace, automotive, and marine industries. Also, these fluids comprise one of the key technological components in electricity generation from concentrating solar power systems (CSPs), where they can store thermal energy as a sensible heat reservoir for later delivery to the power conversion system in absence of solar radiation. Here the authors, have developed a new one pot strategy towards biarylated ethers as novel Heat Transfer Fluids while using minimal amount of reaction solvent. The physical properties of these fluids will be discussed and compared to calculated values gained from different computational models. The use of the fluids in Solar Thermal Energy Generation will be indicated.
