1), show smaller changes in lifetimes with shortening in the case of dimers compared to monomers and little differences before and after fusion (Fig. 5c, Supplementary Figs. 17 and 21) the notable lifetime shortening that is seen for the small CQD molecules upon fusion is indicative of the ...
Comparing the arrangement of the molecules before and after manipulation reveals very similar patterns of close contacts between the molecules, showing that intermolecular LD interactions have a significant influence on the process of molecular assembly. Fig. 6 Constant height AFM scans of a molecular ...
12 After the unique and synthetically challenging β-lactam structure of penicillin had been revealed by X-ray crystallography in 1945, it was not until 12 years later that its first total synthesis was achieved.13 Despite inevitable emergence of bacterial resistance, penicillin and a multitude of ...
Before Dr Meldal and Dr Sharpless applied themselves independently to the matter in 2001 and 2002, the reaction between azides and alkynes was known to work, but only slowly and with a tendency to yield a mixture of products. They sought to change that and, after a bit of experimentation, ...
25,59, 60, 61, 62, 63, 64, 65, 66, 67 Before carrying out a more focused investigation toward INVEST molecules with appreciable fluorescence rates, we tested a few modifications of molecules 1 and 2 to find out what structural features would make the singlet-triplet gap positive. One ...
If you like, you can also use this folder and compare to your results.Take your time to read the tasks carefully before proceeding to actually prepare the calculations. Each subtask starts with a short summary (gray box) and gives details and hints afterwards. Also, feel free to consult ...

A chemical deprotection strategy based on the inverse-electron-demand Diels–Alder ligation. After the initial ligation of an allylictrans-cyclooctene to a tetrazine, the intermediate pyridazine can rearrange to warrant the elimination (release) of the allylic substituent. Carbamates, as well as ethers...
the change in overlap between two wavefunctions after a small nuclear displacement. If the NACV between two states is zero, then their wavefunctions must change slowly in response to a nuclear perturbation. Therefore, their energies cannot form the cusp in Fig.1(a), and must instead resemble...
