Abstract:
Two water/alcohol soluble conjugated polymers (WSCPs), based on naphthalenediimide and amino-functionalized 3,4-(propylenedioxy)thiophene, were synthesized via direct arylation polycondensation (DArP). The polymers worked well as electron transporting layers (ETLs) for fullerene-based and fullerene-free organic solar cells (OSCs), presenting an enhancement by above 40% compared to the control devices, respectively. The doping properties and high electron mobilities of these WSCPs endow them with high performance. The research study developed an effective method to synthesize ETLs for highly efficient OSCs, which was rarely reported.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
