Conron S, Shoer L, Smeigh A, Ricks A, Wasielewski M
J Phys Chem B . 2013 Jan; 117(7):2195-204. PMID: 23360435
Two X-shaped, cruciform electron donor(2)-acceptor-acceptor'(2) (D(2)-A-A'(2)) molecules, 1 and 2, in which D = zinc 5-phenyl-10,15,20-tripentylporphyrin (ZnTPnP) or zinc 5,10,15,20-tetraphenylporphyrin (ZnTPP), respectively, A = pyromellitimide (PI), and A' = perylene-3,4:9,10-bis(dicarboximide)...

Mallory F, Mallory C, Regan C, Aspden R, Ricks A, Racowski J, et al.
J Org Chem . 2012 Dec; 78(5):2040-5. PMID: 23205719
In recent years, we have used the photocyclizations of diarylethylenes to synthesize a number of [n]phenacenes in the hope that they might be useful as the bridging groups for electron...

Colvin M, Ricks A, Wasielewski M
J Phys Chem A . 2012 Feb; 116(9):2184-91. PMID: 22335802
The impact of donor-acceptor electronic coupling and bridge energetics on the preference for hole or electron transfer leading to charge recombination in a series of donor-bridge-acceptor (D-B-A) molecules was examined....

Ricks A, Brown K, Wenninger M, Karlen S, Berlin Y, Co D, et al.
J Am Chem Soc . 2012 Feb; 134(10):4581-8. PMID: 22335614
Donor-bridge-acceptor (D-B-A) systems in which a 3,5-dimethyl-4-(9-anthracenyl)julolidine (DMJ-An) chromophore and a naphthalene-1,8:4,5-bis(dicarboximide) (NI) acceptor are linked by oligomeric 2,7-fluorenone (FN(n)) bridges (n = 1-3) have been synthesized. Selective photoexcitation of...

Colvin M, Ricks A, Scott A, Co D, Wasielewski M
J Phys Chem A . 2012 Feb; 116(8):1923-30. PMID: 22296165
Intersystem crossing involving photogenerated strongly spin exchange-coupled radical ion pairs in a series of donor-bridge-acceptor molecules was examined. These molecules have a 3,5-dimethyl-4-(9-anthracenyl)-julolidine (DMJ-An) donor either connected directly or connected...

Colvin M, Smeigh A, Giacobbe E, Conron S, Ricks A, Wasielewski M
J Phys Chem A . 2011 Jun; 115(26):7538-49. PMID: 21630656
tert-Butylphenylnitroxide (BPNO(•)) and α,γ-bisdiphenylene-β-phenylallyl (BDPA(•)) stable radicals are each attached to zinc meso-tetraphenylporphyrin (ZnTPP) at a fixed distance using one of the ZnTPP phenyl groups. BPNO(•) and BDPA(•) are oriented...

Colvin M, Ricks A, Scott A, Smeigh A, Carmieli R, Miura T, et al.
J Am Chem Soc . 2010 Dec; 133(5):1240-3. PMID: 21192109
A covalent, fixed-distance donor-bridge-acceptor (D-B-A) molecule was synthesized that upon photoexcitation undergoes ultrafast charge separation to yield a radical ion pair (RP) in which the spin-spin exchange interaction (2J) between...

Ricks A, Solomon G, Colvin M, Scott A, Chen K, Ratner M, et al.
J Am Chem Soc . 2010 Oct; 132(43):15427-34. PMID: 20942407
Photoinitiated charge separation (CS) and recombination (CR) in a series of donor-bridge-acceptor (D-B-A) molecules with cross-conjugated, linearly conjugated, and saturated bridges have been compared and contrasted using time-resolved spectroscopy. The...

Scott A, Ricks A, Colvin M, Wasielewski M
Angew Chem Int Ed Engl . 2010 Mar; 49(16):2904-8. PMID: 20232431
Burning bridges: The exponential distance dependence (β value) of singlet and triplet charge recombination (CR) pathways is determined for three donor-bridge-acceptor (DBA) molecules. p-Phenylethynylene and fluorenone bridges have similar β...

J Am Chem Soc . 2009 Nov; 131(48):17655-66. PMID: 19904984
A series of donor-bridge-acceptor (D-B-A) triads have been synthesized in which the donor, 3,5-dimethyl-4-(9-anthracenyl)julolidine (DMJ-An), and the acceptor, naphthalene-1,8:4,5-bis(dicarboximide) (NI), are linked by p-oligophenylene (Ph(n)) bridging units (n = 1-5)....
