Molecular LEGO blocks having two reversible covalent bond moieties were employed to synthesize corresponding molecular LEGO block polymers.
The hexyl-substituted phenoxazine was selected as donor moiety and diphenyl-1,3,4-oxadiazole or fluorene-containing moieties were employed as electron-acceptor groups, being connected via the imine bond.
In this ratiometric sensor, GMP/Tb moiety was employed as response signal due to the ON-OFF-ON behaviors of Tb3+ fluorescence upon the sequential addition of Cu2+ and H2S, while CDs@ZIF-8 served as reference signal because of the good stability of CDs fluorescence in the presence of Cu2+ or/and H2S.
Through our synthetic design rationale, the planar and fused BTT moiety was employed as an electron-rich co-monomer in conjunction with the electron-deficient BTI unit to create a highly absorptive π-conjugated polymer with an ideal band gap of roughly 1.5 eV and optimum frontier energy levels allowing for efficient charge transfer to a fullerene and a high open circuit voltage.
In the case of thiamine biosynthesis, an additional radical SAM enzyme ThiH is employed to ultimately synthesize the thiazole-P carboxylate moiety of thiamine phosphate (section 10.1).
The recently developed approach of Transition Moment Orientation Analysis is employed to determine the three dimensional orientation and order of the different molecular moieties in semi-crystalline polyolefins.
Various targeting moieties have been employed to facilitate tumour targeting, such as affibodies, peptides, conventional monoclonal antibodies (mAbs) or antibody fragments.
In certain cases such as 4-pyridyl derivatives, the separation of diastereoisomers as menthone ketals is difficult, and thus other chiral moieties have been employed.
The two-photon fluorescent probe 2, which contains the di-2-picolylamine (DPA) as a Zn2+-binding site, the naphthalimide unit as the two-photon fluorophore, and the ifenprodil-like tail as the NMDA receptor binding moiety, can be employed for selective detection of Zn2+ located near the NMDA receptor and for monitoring concentration changes of Zn2+ in live neurons and hippocampal tissues.
Microcontact printing, one of the most conventionally used soft lithography methods to prepare patterns with a chemical moiety, has been employed to create cellular patterns on both planar and nonplanar surfaces, by delivering anchor molecules using a polydimethylsiloxane (PDMS) stamp [ 45].
