Abstract: Compositions and methods for forming titanium-containing thin films are provided. The compositions comprise at least one precursor selected from the group consisting of (methylcyclopentadienyl)Ti(NMe2)3, (ethylcyclopentadienyl)Ti(NMe2)3, (isopropylcyclopentadienyl)Ti(NMe2)3, (methylcyclopentadienyl)Ti(NEt2)3, (methylcyclopentadienyl)Ti(NMeEt)3, (ethylcyclopentadienyl)Ti(NMeEt)3 and (methylcyclopentadienyl)Ti(OMe)3; and at least one liquification co-factor other than the at least one precursor; wherein the at least one liquification co-factor is present in amount sufficient to co-act with the at least one precursor, and in combination with the at least one precursor, forms a liquid composition.
