Coupled exciton model with off-diagonal disorder for optical excitations in extended dendrimers [PDF]
Phys. Chem. Chem. Phys. 1 (1999) 1687-1689, 1998 A phenomenological coupled exciton model is proposed in order to characterize optical excitations in extended dendrimers. An onsite exciton state is assigned at each phenyl rings and a nearest neighbor hopping integral which obeys the Gaussian distribution is considered between the exciton states.

Charge-induced conformational changes of dendrimers [PDF]
Macromolecules 41, 4452 - 4458 (2008), 2008 We study the effect of chargeable monomers on the conformation of dendrimers of low generation by computer simulations, employing bare Coulomb interactions. The presence of the latter leads to an increase in size of the dendrimer due to a combined effect of electrostatic repulsion and the presence of counterions within the dendrimer, and also enhances ...

Extracellular Matrix Targeted MRI Probes
Analysis &Sensing, Volume 3, Issue 1, January 2023., 2023 Gadolinium based MRI probes targeted to ECM components, either proteins or enzymes, hold promise for accurate molecular characterization and staging of fibrotic diseases in vivo. Non‐covalent binding probes (1), reactive probes (2), and enzyme‐responsive probes (3) are discussed.

Anomalous behavior of trapping in extended dendrimers with a perfect trap [PDF]
The Journal of Chemical Physics 143, 064901 (2015), 2015 Compact and extended dendrimers are two important classes of dendritic polymers. The impact of the underlying structure of compact dendrimers on dynamical processes has been much studied, yet the relation between the dynamical and structural properties of extended dendrimers remains not well understood.
