Temperature-Dependent Dual Fluorescence from Small Organic Molecules

چکیده
The temperature-dependent dual fluorescence from a single component of small organic molecules (SOMs) is very promising for the ratiometric sensing temperature. However, SOM-based fluorophores typically only show one band. It thus challenging to achieve fluorescence, let alone that sensitive Herein, in this short review, we briefly summarized examples exhibiting fluorescence. Through representative examples, mainly focus on illustration intrinsic mechanisms unusual phenomenon, which may take place because presence two local minimum conformations are thermally equilibrated ground state, first excited state as result significant structural relaxation upon excitation, or thermal equilibrium between and second states. Hopefully, discussions review will provide some important guidelines further rational molecular design such fluorophores.

متن کاملAtomic force microscopy characterization of room-temperature adlayers of small organic molecules through graphene templating.
We report on the use of graphene templating to investigate the room-temperature structure and dynamics of weakly bound adlayers at the interfaces between solids and vapors of small organic molecules. Monolayer graphene sheets are employed to preserve and template molecularly thin adlayers of tetrahydrofuran (THF) and cyclohexane on atomically flat mica substrates, thus permitting a structural c...

We report an implementation for the computation of optical rotations within the Amsterdam Density Functional program package. The code is based on time-dependent density functional response theory. Optical rotations have been calculated for a test set of 36 organic molecules with various density functionals, and employing basis sets of different quality. The results obtained in this work with n...
متن کاملUnusual assembly of small organic building molecules in common solvent.
During the process of self-association, reaching a thermodynamic equilibrium state in dilute solution is usually very fast, taking at most seconds for small organic (such as surfactants) solutions and hours for polymer solutions. It is very rare that days are necessary for soluble small organic molecules to reach thermodynamic stability in dilute solutions. This work reports such an unusually s...
