Lin H, Yao C, Li J, Gunaratne H, Singh W, Huang M, et al.
JACS Au
. 2023 Sep;
3(8):2257-2268.
PMID: 37654579
A recurring dream of molecular recognition is to create receptors that distinguish between closely related targets with sufficient accuracy, especially in water. The more useful the targets, the more valuable...

Chempluschem
. 2022 Dec;
88(4):e202200362.
PMID: 36456470
The general tool of fluorescent PET (photoinduced electron transfer) sensors/switches - a molecular design principle with engineering features - is outlined, with the aid of frontier orbital energy diagrams. Fluorophores...

Yao C, Lin H, Morgenfurt P, Keyes T, de Silva A
Chem Sci
. 2022 Nov;
13(36):10856-10867.
PMID: 36320709
Shape-switchable cyclophane hosts allow the controlled capture and release of reactive polypyridineRu(ii) complexes in water. This gives rise to a network of host-guest binding, acid-base reactions in ground and excited...

Yao C, Lin H, Daly B, Xu Y, Singh W, Gunaratne H, et al.
J Am Chem Soc
. 2022 Mar;
144(11):4977-4988.
PMID: 35274938
Electron/proton transfers in water proceeding from ground/excited states are the elementary reactions of chemistry. These reactions of an iconic class of molecules─polypyridineRu(II)─are now controlled by capturing or releasing three of...

West M, Yao C, Melaugh G, Kawamoto K, Uchiyama S, de Silva A
Chemistry
. 2021 Jul;
27(52):13268-13274.
PMID: 34233035
Temperature-driven fluorescent NOT logic is demonstrated by exploiting predissociation in a 1,3,5-trisubstituted Δ -pyrazoline on its own and when grafted onto silica microparticles. Related Δ -pyrazolines become proton-driven YES and...

Angew Chem Int Ed Engl
. 2021 Mar;
60(25):13819-13823.
PMID: 33723888
A colorimetric indicator displacement assay (IDA) amenable to high-throughput experimentation was developed to determine the percentage of cis and trans alkenes. Using 96-well plates two steps are performed: a reaction...

Chemistry
. 2019 Apr;
25(36):8522-8527.
PMID: 30947361
One of the challenges for fluorescent sensors is to reduce their target environment size from a micrometer scale, such as biological cells, to a nanometer scale. Proton maps near membranes...
